The April 2019 issue of Plant Physiology includes a set of papers addressing biotic interactions between plant and pathogens or pests. As the editors indicate, progress on this topic has been rapid and significant. Key topics explored in reviews and research articles include: the roles of plant hormones,…

A strikingly vast array of phylogenetically distant plants are able to form intimate interactions with symbiotic arbuscular mycorrhizal (AM) fungi for the mutually beneficial exchange of nutrients. Several years of intensive research have revealed the complex regulatory networks and genetic ‘toolkits’…

The nematode infection process in plants involves secreted effector proteins that suppress the host defense mechanisms. However, the molecular interactions in which this is done is yet unclear. Here, Pogorelko et al. characterize the function of 4E02, an effector from the cyst nematode H. schachtii,…

To secure food availability for the world population, plant scientists study the interactions between crop species and pathogens. Plants have robust defense strategies that they employ when attacked. On the other hand, microbes have multiple strategies to manipulate host functions to suppress these defenses…

Herbivore-induced volatiles have been shown to prime plant defense response in multiple species. A new study by Ye et al. unveils some of the early signaling events in volatile-mediated defense priming in rice. The authors show that rice plants release increased amounts of the volatile indole when attacked…

To fight off invading pathogens, higher plants such as Arabidopsis are intrinsically programmed with a subset of defense responses known as pattern-triggered immunity (PTI). However, excessive defense responses may hamper plant’s normal growth, so fine-tuning PTI is important for plant survival. Recently,…

Chloroplasts have diverse roles in plant defense, including contributing to the production of defense compounds. Toufexi, Duggan et al. show new data indicating the dynamic relocation of chloroplasts to the contact point of the oomycete pathogen Phytophthora infestans. Infection also causes an increase…

As an important plant hormone, jasmonic acid regulates plant defense responses and adaptive growth. When the plant is exposed to pests or other stresses, the active jasmonic…
